FEBRUARY 7, 2007 -- Prysmian Cables & Systems (search for Prysmian) has introduced CasaLight, its new 'bend insensitive' optical fiber in accordance with ITU-T Recommendation G.657.
With the rapid growth in broadband services and the corresponding need to upgrade 'last mile' telecoms infrastructures, there is a growing trend to deploy optical fiber closer and closer to the end user. This transition towards the ultimate goal of fiber-to-the-home (search for FTTH) means that the optical fiber is likely to encounter greater levels of handling and will be subjected to more extreme degrees of bending than previously experienced.
The recently issued ITU-T Recommendation G.657, entitled "Characteristics of a Bending Loss Insensitive Single Mode optical Fiber and Cable for the Access Network," defines the new and tougher performance requirements now demanded by these applications. According to Prysmian representatives, CasaLight meets all of these requirements, and in particular:
Prysmian representatives say the addition of the CasaLight fiber to its portfolio further strengthens its position as a world leader in optical fiber technology.
